They're probably interested in reducing outgoing spam -- these sorts of
checks improve their chances of blocking junk; albeit they will prevent
perfectly sensible configurations from working :(

You may need to change to another provider if your view of sensible
fails to accord with theirs.

... that said, you certainly want to have (and it is reasonable for an
ISP to insist upon) a routeable address for the SMTP sender because
otherwise it's impossible to send you any delivery status notifications
(or other bounces).

It's also pretty unwise to have the Reply-To: unrouteable! though that's
your problem rather than that of worldwide mail systems!

Then let us hope that you never stay online for more than a few seconds
(so you cannot pollute the Internet for the rest of us) or have any
personal data on your machine that you'd be loth to pass on to others :(
